**Have you ever wondered what makes Roller-coasters go?**Well it’s Energy. There are two types of Energy on a roller-coaster.One is the energy of motion, Kinetic Energy(K.E.) the energy of motion. The other is Gravitational Potential Energy(G.P.E.), the energy that has the potential to fall.At the start there is no G.P.E. but it starts building up the higher it goes, then at the top of the first hill it has all the G.P.E. because it’s at the highest point and there will never be as much G.P.E. as this ever again because the roller coaster can't go up as high, unless it had a rocket. After the big hill the coaster will get more K.E. because the hill gave it enough force to move but on it's way down it will lose all G.P.E. At the top of the lop there is now more G.P.E. and still has as much K.E.because it is still moving , but after it falls there is no G.P.E. and a little more K.E. At the last hill there is a little G.P.E., but not as much as the K.E. This is how energy works on the roller-coaster and then other people get on and it starts all over again.
